Barely Legal - S5-E8
Continuity mistake: When Meg is introducing Brian to Meg's friends, they are at the mall sitting at a table with trays on it. There's a close-up on one of Meg's friends, and the trays and food are gone. (00:12:40)
Continuity mistake: When the family is in the traffic jam there's a shot from the front of the car, and in the next shot from the backseat of the car, Peter's face (glasses and part of nose) is reflected in the rear view mirror. However, there's no rear view mirror in the first front shot or shots following backseat shot.
Other mistake: The 'KISS' logo above Kiss's stage isn't actually held up by anything.
Audio problem: In the scene where Quagmire is bidding on the prostitutes panties, the auctioneer says that she had 9 STDs, but the closed captions have him saying, "She had 12 STDs." (00:03:20)
Continuity mistake: When Peter is pretending to be a man-eating tree, there is more of a shadow on the tree in the first shot than in the shot right after he spits out 'Dan Rather'. (00:05:50)
Brian Wallows and Peter's Swallows - S3-E17
Audio problem: The keys that Jonas hits don't correspond to the music we hear. (00:01:15)
Continuity mistake: When Brian is sitting on the deckchair reading 'Utne Reader', the words 'Utne Reader' switch from being on the front cover, to the back cover, and then to the front again. (00:07:40)
Family Guy Viewer Mail #1 - S3-E21
Continuity mistake: When we first see the crowd in the 'We Hate Broads' club, there is a boy with a red hat standing behind a black boy, but in the next shot, they are standing next to each other. (00:15:00)
Continuity mistake: The position of the hole on the leg of Meg's pants changes. In the scene where Meg is putting the mouse traps around Joe, the hole is on the right side. When they arrive at the house with Randy Newman and Meg is telling Peter that the Twinkee factory in Natick may not even exist, the hole is on the left side. This happens again throughout the episode. (00:10:55 - 00:12:30)
To Live and Die in Dixie - S3-E12
Continuity mistake: When Lois is on the phone to the FBI agent, the phone switches from being an old fashioned circular dial phone, to being a keypad phone. (00:16:45)
Continuity mistake: When the Grinch drops the sack, the sack lands next to him, but in the next shot, it is gone. (00:11:45)
Continuity mistake: When Stewie is golfing and spots Brian in disguise, Stewie has a putter. When Stewie realizes that it is Brian and goes after him he is holding a chipper.
I Never Met the Dead Man - S1-E2
Continuity mistake: When Peter is explaining to Meg about "bribes" in one shot the window in the kitchen door disappears. (00:09:00)
Continuity mistake: Just before Peter enters the tunnel in his new car, the white line in the middle of the road is blotchy and not continuous. When the shot changes to Peter's POV, the line has completely disappeared. The next shot which shows the car side on, there is now a straight white line on the road. (00:14:20)
Other mistake: When Peter is dancing to his musical number on top of the table, his head continually shrinks until the end of the shot, where his head is around a third of what it was originally.
One If By Clam, Two If By Sea - S3-E4
Continuity mistake: After Peter has been to the newly opened bar, he runs to his house door (which is red) and when he opens it, the colour has changed to brown.
Continuity mistake: During the Star Wars rip-off at the end, just before Peter climbs the Town Hall stairs, the people on the sidelines change. (00:19:45)
Peter Griffin: Husband, Father...Brother? - S3-E14
Continuity mistake: When Stewie jumps on the picnic table and begins his dance, at one point he undoes his coveralls and removes his shirt. In the next shot he is fully clothed.
Factual error: When Stewie is playing Simon Says, the sequence Stewie plays is different than the one that the Simon Says played. If he played it wrong, there should have been a sound from the Simon Says indicating that Stewie played it wrong.
Answer: Mort is Jewish, and Walt Disney was said to be antisemitic. So it would make sense in a Disney universe all the inhabitants would share his supposed beliefs.
